More evidence that houseplants clean our air.

The experiment was conducted by Dennis Decoteau of Penn State’s Department of Horticulture with a snake plant, spider plant, and golden pothos inside “experimental chambers in a greenhouse equipped with a charcoal filtration air supply system to measure ozone depletion rates.”

While it took 75 minutes for ozone levels to come down in plantless chambers, air in chambers with plants reached the target in just 50 minutes. He speculates the plants take in the ozone through their stomates (tiny pores used for gas exchange) and then break it down once inside the plant.

The article also recommended keeping plants in our rooms because:

* Plant-filled rooms contain up to 60 percent fewer airborne molds and bacteria than rooms without plants, studies show.

* People who work in offices with windows and plants are happier than others, according to a study of 450 office workers in Texas and the Midwest. In fact, 82 percent of the participants who worked with plants and windows around said they felt “content” or “very happy,” compared with 58 percent in windowless plant-less offices who said the same.

* Plants seem to make people more contemplative and self-reflective, according to one ethnologist.

My sinuses have cleared since I put houseplants in my bedroom (since January actually). To date, we have a large Areca Palm (temperamental thing), 2 Snake Plants (hardy), 6 Corn Plants (easiest to manage), and 1 Spider Plant (who goes out for sun and rotates with its brethren outside). These are ideal for an air conditioned bedroom in the tropics. My poor Peace Lily just died. RIP dear fellow.
